MateCat
Pros
- + Truly free with unlimited users, projects and storage — no word meter at all, unlike Smartcat's 15,000-Smartword monthly cap on free AI translation.
- + ModernMT adaptive machine translation is the default engine for logged-in users at no cost, learns from your edits in real time, and carries a 100,000-word context window across 200 languages.
- + MyMemory — around 12 billion words of public translation memory — is preloaded, giving fuzzy-match coverage from the first segment.
- + Zero-friction access: single files translate with no registration at all, entirely in the browser, across 80 file formats with the format preserved on download (documented exceptions for iWorks and PDF).
- + Open source under the LGPL and self-hostable, with a REST API (projects up to 600 files at 200 MB each), open standards (XLIFF, TMX) and open APIs for external TMS and MT connections.
Cons
- - Vendor documentation contradicts itself on fundamentals — 70 vs 80 vs 82 file formats and 90 vs 200+ languages across its own pages — which makes pre-purchase verification unnecessarily manual.
- - On the hosted service, source files, segments, translation memories and outputs all live on Translated's servers; self-hosting means a manual Ubuntu install with no maintained cloud image.
- - The MT features that matter most for production shops — glossary enforcement in MT, pretranslation adaptivity, TM optimisation — are gated behind paid ModernMT licences.
- - Thin translation-management layer: no linguist marketplace, limited workflow and permission controls, and collaboration described as basic by independent comparisons.
- - Single-vendor dependence: development and hosting rest with Translated srl, whose business model is translation outsourcing and ModernMT licences — free support has no SLA and no paid tier exists to buy one.
Lilt
Pros
- + Adaptive models absorb linguist corrections in real time — in my testing the engine repeated my approved branded term within the same session
- + Git connectors (GitHub, GitLab, Bitbucket) move strings in and out of repos so translation happens inside the pull-request flow
- + Human verification is part of the platform rather than a bolt-on marketplace, with agents pre-fixing errors before human review
- + Named a Leader in The Forrester Wave: Translation Management Systems, Q3 2025 with top scores in 13 of 26 criteria (per Lilt's account)
- + Deployment options include private, on-prem and air-gapped setups with forward-deployed engineers for regulated buyers
Cons
- - No published pricing at all — everything is quoted per program, so budgeting requires completing a sales cycle
- - No self-serve tier or free trial; completely unsuited to one-off or occasional translation jobs
- - Connector and workflow integration is real implementation work before the first translated string arrives
- - Quality of adaptive output depends on the quality of the linguist pool correcting it — the human layer is a recurring cost
- - Vendor comparison claims about competitor pricing and rush fees are unverifiable and I do not credit them
